Meningitis

A map of the world showing different things. Countries in red: Meningitis is common (So-called meningitis belt in Africa). Countries in brown: Sometimes there are epidemics of meningitis. Countries in grey: They may be a few cases of meningitis, each year. Note the map is not completely accurate though.

The two main forms of meningitis are bacterial meningitis and viral meningitis. In bacterial meningitis, most patients die without treatment, whereas in viral meningitis most patients get better on their own. Herpes virus meningitis may respond to an antiviral drug.[1]
